PRESSURE WHILE REAMING
PRESSURE GRAVITY TOOL
FOR HORIZONTAL DIRECTIONAL DRILLING
The Pressure Gravity Tool (PGT) is a stand-alone probe providing the same real-time monitoring of annular and pipe pressure you get from the Pressure Module when drilling the pilot hole, but with an upgraded digital accelerometer that provides instantaneous RPM feedback at the reamer at a higher sample rate than typically provided by survey tools.
With pressure and rotation plotted in RivCross software, the driller receives immediate feedback of downhole reaming performance, reducing the occurrence of costly twist-offs and inadvertent returns. All pressure and rotational data is logged to the permanent RivCross job database for verification that project tolerances have been met.
Compatible with standard pressure components and straightforward to deploy, the PGT provides an immediate ROI through improved productivity while providing accountability for the most challenging reaming jobs.
